1. An exercise machine comprising:
- a framework means, said framework means configured to be supported by the floor and support a seat means;
a pedal means, said pedal means configured for each foot of a seated operator;
a linkage means having first and second ends and having a crank means connected intermediate said ends and projecting outwardly therefrom on both sides thereof, said crank means rotatably connected to said framework means;
a coupling means operably associated with said linkage means and said first end and said framework means;
said pedal means connected to each said linkage means at a second end of said linkage means whereby said pedal means follows a generally elliptical inclined pedal path as said crank means rotates with the foot force acting upon said pedal means of a seated operator positioned in said seat means.

Abstract
An exercise apparatus is provided for sit down exercise operated in the recumbent position where foot operated pedals follow an oblong pedal path coordinated with arm exercise. The pedals are guided by extended foot supports as part of a linkage system that is coupled to the arm exercise. Pedal motion and arm exercise can be adjusted during operation of the exercise apparatus to exercise different muscles. An alternate application of the pedal and arm exercise motion is offered as a propulsion mechanism coupled to the drive train of a land or amphibious exercise apparatus.

12. A recumbent exercise machine comprising:
a framework means, said framework means configured to be supported by the floor and support a seat means; a pedal means, said pedal means configured for each foot of a recumbent operator; a linkage means having a crank means projecting outwardly therefrom on both sides thereof, said crank means rotatably connected to said framework means; a coupling means operably associated with said linkage means and said framework means; said pedal means connected to each said linkage means whereby said pedal means follows a generally oblong inclined pedal path as said crank means rotates with the foot force acting upon said pedal means of a recumbent operator positioned in said seat means; an actuator means connected to said coupling means on one end and operably associated with the framework on the other whereby the coupling means connection to said framework means can be moved during operation of said exercise machine thereby causing said oblong inclined pedal path to change. - View Dependent Claims (13, 14, 15, 16, 17)

18. A recumbent exercise machine comprising:
a framework means, said framework means configured to be supported by the floor and support a seat means; a crankshaft bearing housing means connected to said framework means and having a crank means projecting outwardly therefrom on both sides thereof; a crossarm means having first and second ends, said crossarm means having a first crossarm pivot means intermediate said ends and connected to each said crank means and a second crossarm pivot means connected to a pivot guide means at one of said ends and operably associated with said framework means; a pedal means connected to each said crossarm means at said other end whereby said pedal means follows a generally elliptical pedal path as said crank means rotates with the foot force acting upon said pedal means of a recumbent operator positioned in said seat means, said foot force acting generally tangent to uppermost portion of said elliptical pedal path. - View Dependent Claims (19, 20, 21, 22, 23, 24)

25. An exercise machine comprising:
a framework means, said framework means configured to be supported by the floor and support a seat means; a handle means, said handle means configured for each hand of a seated operator; a linkage means having a crank means projecting outwardly therefrom on both sides thereof, said crank means rotatably connected to said framework means; a coupling means operably associated with said linkage means and said framework means; said handle means connected to each said linkage means whereby said handle means follows an extended closed loop hand path as said crank means rotates with the hand force acting upon said handle means of an operator positioned in said seat means; and
an actuator means connected to said coupling means on one end and operably associated with the framework on the other end, whereby said coupling means connection can be moved during operation of said exercise machine thereby causing said elongated closed loop hand path to change.- View Dependent Claims (26, 27, 28, 29, 30, 31)
